The digital television (DTV) transition refers to the switch from analog to digital broadcast television. All full-power television stations have stopped broadcasting in analog, and now broadcast only in digital. If you aren’t receiving digital signals on your analog TV, you can purchase a digital-to-analog converter box from an electronics retailer.
If you are having difficulty receiving digital broadcast stations in your area, this troubleshooting guide provides a connections checklist and tips on reception of digital signals.
Use an Antenna that Provides Good Reception of All Channels
- Most existing antennas used by consumers will provide good reception of DTV signals. (Before making any changes, try your existing antenna first to see of it allows you to receive all the stations you normally watch.)
- For watching DTV signals, you will need an antenna that provides good reception of both VHF signals (channels 2-13) and UHF signals (channels 14-51) to reliably receive all of the digital signals broadcast in your area.
- Many antennas are designed only for reception of either VHF or UHF signals (but not both). For example, the commonly used “rabbit ears” indoor antenna is only suitable for receiving VHF signals. To receive UHF signals, an indoor antenna should also include a wire loop or other feature for reception in that band.
- The reception capabilities of TV antennas also vary considerably, so be sure to talk to retail consultants and look at information on the packaging and/or the Internet to make sure that any new antenna you may choose provides good reception of both VHF and UHF channels. In addition, if you use an indoor antenna and receive signals on VHF channels, you may need to use an antenna with amplification.
- Many antennas currently being sold as “HDTV Antennas, ” perform best at receiving UHF signals; some of these models state that they provide reception of signals on channels 7-13 but actually perform less well receiving those channels. If you obtain one of these antennas, be sure it provides good reception of all the VHF channels as well as the UHF channels.
Check Your Connections
- Check that your digital-to-analog converter box or digital television is connected properly. Make sure your antenna is connected to the antenna input of your digital-to-analog converter box or digital television. If using a digital-to-analog converter box, also ensure that the antenna output of your converter box is connected to the antenna input of your analog TV. Refer to the owner’s manuals of your components if you are unsure of the proper connections.
- Ensure that your components are plugged in and have their power turned on.
- If you have a digital-to-analog converter box, tune your analog TV to channel 3. You should see a set-up menu or picture displayed on your TV screen. If you do not see a set-up menu or picture, tune your TV to channel 4. If you still do not see a set-up menu or picture, recheck your connections.
Perform a Channel Scan
- Digital-to-analog converter boxes and digital televisions have a button, usually on the remote control, that is labeled “set-up” or “menu” or some similar term. Press that button to access the set-up menu.
Using the directional arrow buttons on your remote, scroll to the option that allows you to perform a “channel scan.” The channel scan will automatically search for digital broadcast channels that are available in your area. Consult the owner’s manual of your digital-to-analog converter box or digital television for detailed instructions on how to perform a channel scan for your device.
- Once the channel scan is complete, you will be able to tune to the digital channels received by your antenna. You should perform a channel scan periodically to check whether additional digital channels have become available.
